In the present machine the sewing mechanisn'ros a whole is fixed in position and a shoe supporting jack is provided which is movably mounted in the machine to enable the shoe to he moved laterally in the direction or". teed to transfer the point of operation about the shoe and'laterally transversely of the direction of feed to maintain the edge of the shoe bottom in the proper" lateral position with relation to the sewing mechanism and to be.

The gimbal rlng 44 1n turn 1s pivoted to swing upon bearing pins 46 mounted in the ring and having their outer'ends, engaging 1n hearings in a wheel 48. Thecommon axis" of the bearing'pins42 is preferably located substantially at right angles to the common axis of the bearing pins 46 so. that the shell and the jack spindle can, swing in any direction 'about its connections with the wheel 48. The wheel 48 is mounted to rot-ate on a vertical hollow stud or sleeve 50 which is' secured by a clamp 52 to'the forward ends r 56 is pivotally connected "with thefyoke 60 to swing in a vertical plane by means of bearing pins 62. Th'e yo'ke' 60is provided with spaced arms64 which embrace a link frame and tne yoke is'pivotally connected with the link frame: to swing in ahorizontal plane by means. of bearing pins 68; The link frame 66 is pivotally connected at 70 with the end of a supporting arm 72 pivotally mounted upon a vertical shaft 74 and is .pivotally connected at 76 with the end of a second supporting arm 78 pivotally mounted upon a vertical stud 80. The supportingarms 72 and 78 are of substantially the same length 'end with an 211l1] 86 on the yoke 56.

and the'yoke 60 is pivotally connected with the link frame 66' at substantially the central point of the link frame. The yoke 60 thus is supported vertically but is free to move forwardly and rearwardly and to swing in a horizontal plane about its pivotal connection with the link ,'lra1nc, this connectionmoving' substantially in a straight li-neperpen dicular to the vertical plane of the lineot feed of the machine during tho forward and rearward movements of the yoke. In order to support the jack spindle and at the time'to permit it to move vertically to accommodate itself tot-he necessary variations in the vertical position of the shoe, a coiled springSZ is connected atone end with an arm 84 on the yoke 60 and at other lit willbe noted that thedevices for sup porting the jack spindles are constructed to enable the lower end of the spindle to be moved horizontally in any direction "and that the connection between the lower end of tne spindle and the devices for supporting the same will permit the upperend of the jack and the shoe to be moved horizontally in any direction independently of the lower end of the Jack spindle- During the sewing operation the shoe is co a second yoke 60 and the yoke held positively to the machineat alltimes during each cycle of operations by the needle, welt guide and channel. guide roll. Relatively slight vertical movements are imparted to the shoe by the action of the spring 82 on [the jack and byfthe engagment of the channel guideroll and welt guide with the shoe, thesepa-rts acting as guides on the shoe.

imparted to the shoe; by devices actingon 7 The requiredv tipping movements are the-jack spindle to move the lower endiof v the spindle forwardly, rearwardlyand laterally of the-machine in: horizontal directions, and the lateral turning movements are impartedto the shoe by devices acting on the jack spindle to rotate the'spindles .Be-

cause of the fact that the shoe is held at;

all times at the point of operation by "the needle, channel guide roll and'welt guide the tipping and turning. movements are caused to take place about-the point of operation. In. the present constructionthe lateral tipping movements of theshoe are produced 1 by the; forward and rearward swinging movements ot the arm 72 which through the connection described between the arm.

and the lower end of the jack spindle impart forward and rearward movements 7 to the lower end; of the spindle, thereby tipping the jack laterally. In the construction shown, (see Figs. 1, 2, 5 and 6) acamlroll supporting lever 88 is pivoted atone end by means of a stud 90 to the arm and connected at its opposite endby a link 92 with a stationary arm'94, said arm being" formed on a bracket 96secured to the frame ofthe' machine. The lever 88 carries a cam roll 98 whichengages in a cam groove 100 in a cam disk 102 mounted on a cam shaft 104 which, for the sake of convenience, will be hereinaftertermed the pattern cam shaft. By the action of the cam groove 100 on the cam roll 98 the lever 88 is actuated to impart forward and rearward swinging movements to the arm 72 and thereby to'impart through the connections described therequired lateral. tipping movements to the jack. 7

Longitudinal tipping movements are imparted to the jack and the shoe by swinging the jack supporting yokes 60 and 56 horizontally. about the bearing pins 68 thereby im artin movements to, the lower end of the jack spindle laterally of the machine. The required swinging movements are imparted to thejack supporting yokes (see Figs. 5 and ,6) by means of a cam actuated bell crank lever 106 pivoted on the shaft 74 through a link 108 connecting the forwardly erztending arm of the bell crank lever with an arm 110 on the yoke 56. A cam' roll supporting lever. 112 is pivoted atone end by means of a stud 114 to the laterally extending arm of the bell crank106 andis connected at its other end by slink 116 with l c ens ;c l;isl,102., Thi bughtheaction o t-the cam and thebell crank lever 106 areactuated to Vi impart throughthe link 108 SWlIIglIIg I HOVB-D groovel22 on the cam roll 120; the lever 112 i ments to thejack supporting yolies 56' and movements to the jack.

The lateral turning movementsof the jack I and the shoe are producedby-imparting turning movements to the Wheel 4 8 about the stud-50. The required 'turning'movements are imparted to the;vvheel,(see Figs.

frame of the machine and a'weight 368'is suspended at the other end of the cable. The Weight 368 through its action on the cable 360 tends to swinglthe' feedinglever 318 and the forward end of the triangular lever 330 to the right and thus tends "to swing the rear end of the lever 33.0 and the intermediate lever 344 to the left. The

The cam face 358 is preferably formed that the triangular lever 330 is actuated to move the feeding lever 318 and through said" lever to actuate tliejack to feed theshoe at a substantially uniform speed past the devices for operating on theasho-e. In the present machine the devices for actuating the jackto feed the shoe are constructer to impart a continuous feeding movement to the shoe; lVith a jack actuating feeding -mechanism of the above construction, the

angular lever 330 and the movement im-' parted thereby to. the feeding lever 318 is adjusted to accord with the size of, the shoe placed in the machine. 'The' mounting of e the fulcrum of tlie triangular lever. 330 upon the lever '340'enables this fulcrum to be shifted forwardlysor rearwardl yto vary" relatively the lengths of the arms of the lever 330. In changing from onesize of shoe to a smaller size "the fulcrum of the 'triangularlever 330 is shifted forwardly so that the movement of thefeeding lever 318 imparted thereto by the lever 330 will be diminished, While inchanging from one size to a larger size the'fulcrum' of the lever 330 is shifted rearwardly to increase the movement imparted by the lever to the lever 318.

The fulcrum of the triangular lever 330 '7 is located substantially in the proper position'for the size of the shoe to be sewn by.

At the time when "the shoe is placed in the machine the fulcrum carrying lever 340 is unlocked'so that it maybe adjustedabout its axis.

Theadjustment of the, feeding lever 318 thus produced will efiect substantially the propel." adjustment of thefulcrun'i of the triangular lever Thus in changing from one'size of shoe to smaller size the feeding lever' 318 willbe swung to the left upon the placing ofithe shoe in the machine in position'to be sewn, the forwardend of the triangular lever 330 will be shifted'to the left with the lever 318 and the fulcrun'ijcarrying lever 340 will be swung forwardly. In a corresponding manner, in changing from one size. of shoe to a larger size the feeding lever 318 will be swung to the right upon the placing of the right therewith and the fulcrum carrying lever 340 will be swung rearwardlv In certain machines the jack actuating feeding mechanism above 'described maybe employed to feed'the shoe without the 00- operation of any other shoe feeding inecha nisin or may constitute the only shoe feeding mechanism of the machine, while in other machines this jack actuating feeding mecha nism may be arranged to cooperate with.
